Cura Sidebar GUI plugin needs your help

[ahoeben 1,963]

I'm the creator of the Sidebar GUI plugin. This plugin puts the settings "floater" in a sidebar like it was in before Cura 4.x, and rearranges some other interface stuff to make things more sensible (in my personal but not entirely uninformed opinion). Recent versions of the plugin even let you undock the sidebar so you can eg move it to a secondary screen.

 

Since Ultimaker Cura 4.9.0, I have had some reports that my plugin makes Cura very slow. Disabling the plugin fixes this slowdown. Unfortunately I am unable to reproduce this dramatic slowdown. I have been trying out some things with one active affected user here on github, but sofar I have not found the silver bullit.

 

If you use this plugin with Cura 4.9.0 (and with over 140.000 downloads, there must be some users out there), please let me know if Cura has become painfully slow after the 4.9 update. If it has, please run `dxdiag` on your system and send me a link to the log it creates, so I can see if there is a common factor between affected users. With luck I'll then be able to reproduce and fix the slowdowns. Other words of appreciation about the plugin are ofcourse also welcome 😉

Personaly I haven't see any difference between an old configuration (Ie 4.7) and the 4.9.0 or 4.9.1

 

Windows 10 

Cura 4.9.1

SideBar GUI 4.1.1

 

Just in the log file some warning messages :

Bonus points for finding the binding loop in the current version. Unfortunately I have fixed this binding loop in a test-version, and that test version is still causing the dramatic slowdown for the affected users.
